The Preparation of Ferroboron and Ferrovanadium by Aluminothermic Reduction
High Temperature Materials and Processes, 1996 The processes for the production of ferroboron and ferrovanadium from indigenous resources by open aluminothermic reduction have been described. The influence of process parameters such as charge composition, particle size, and the use of fluxes on the yield and composition of the ferroalloys obtained are discussed.

Continuous Hot‐Dip Galvanizing of Medium‐Manganese Third‐Generation Advanced High‐Strength Steels
steel research international, Volume 94, Issue 11, November 2023., 2023 Herein, the effects of process atmosphere pO2 on the reactive wetting of two medium‐Mn third‐generation advanced high‐strength steels during continuous hot‐dip galvanizing are interrogated. The substrates are austenitized, flash‐pickled, intercritically annealed, and galvanized in a conventional 0.2 wt% Al (dissolved) bath.

Strontium Extraction by Aluminothermic Reduction
Canadian Metallurgical Quarterly, 1991 AbstractExperiments are performed in a mechanically agitated molten bath of aluminium to extract strontium from strontium carbonate by aluminothermic reduction. The molten aluminium contains additions of magnesium or bismuth. Magnesium is added to the melt for two reasons: to increase the reactivity and to lower the surface tension of the molten alloy.
